Shutting down your Mac and putting it in sleep mode both offer benefits to your Mac. However, if the question is which one is better for daily use—that is, if you only plan to stop using your Mac for a few hours or for the night—then putting your Mac to sleep is the best option.
Open Battery settings for me. Click Options on the right, then do any of the following: Stop automatic sleeping when the display is off: Turn on "Prevent automatic sleeping on power adapter when the display is off.". Put hard disks to sleep: Turn on "Put hard disks to sleep when possible.".The main reason for letting your Mac sleep instead of shutting it down is that your Mac can't perform maintenance tasks during the night if you shut it down. macOS does a lot every night while your Mac isn't being used and it is "sleeping". Apple actually has a term for this sleep mode — " Power Nap ".
